Math LatexView doesn't show on physical iOS Device
Closed this issue · 21 comments
Hi,
I am working on a crossplattform application. On android phones and simulators the latex view shows up and everything works fine. Also if I use I Phone Simulator the view shows up with the correct numbers and equations. But if I load the application on a physical I Phone device all latex views are like empty and they don't show any texts or anything. Normal buttons or labels are working as usual.
This seems to happen to me only on an physical iOS device.
I used the free provisoring which is described here https://docs.microsoft.com/de-de/xamarin/ios/get-started/installation/device-provisioning/free-provisioning?tabs=windows
to deploy it on my I Phone maybe that is the problem cause I don't have developer license yet.
I would appreciate any help. I love this latexmath view and want it to be running without fails on any Phone Thank you for your work.
Unfortunately I don't own physical iPhones so I cannot debug this 😢
Assuming you're using CSharpMath.Forms, this may be a SkiaSharp bug.
Free provisioning is not related to this issue. As you can put your app on an iPhone, this already indicates that it works. Please attach a reproduction solution so that I can search for possible causes.
I don't know what you mean by reproduction solution but here is my code https://we.tl/t-IaNyLZ1Ka7
Try calling InvalidateSurface() on the MathView?
will try it thanks. One other question if you don't mind how can I use a mathview on a button? Is this possible?
@ImadAbuDev What a coincidence! The latest commit ff42032 just added a MathButton - you can copy its source for now until a new release arrives.
The DrawAsStream extension method is defined in https://github.com/verybadcat/CSharpMath/blob/master/CSharpMath.SkiaSharp/Extensions.cs
@Happypig375 that's great! what exactly do I have to copy and where ? since I can't change the NuGet Package content itself
You can copy the code directly to your app, preferably with a different namespace so that class names will not clash when you update.
Ok will try thanks when to expect new release?
I'll publish a new prerelease 0.4.0-beta in the next few days. Did the provided solution work?
@ImadAbuDev Did the solution work for you?
If there is no response, I will consider this question successfully answered.
Sorry for late response haven't tried it yet since I have no I Phone in my Home office (only android) will check when I have access to one. For the button I tried to copy the code but did't work for me properly I will just wait for new release :)
As of 0.4.0-beta, calling InvalidateSurface() will be done automatically. Please check if this is fixed.
Where can I update to beta version in Visual studio?
